Estimating the term…
A hydrogenation catalyst and a preparation method therefor and a use thereof are provided. The hydrogenation catalyst is a sulfided-state hydrogenation catalyst and includes a carrier, an active component A, an active component B, and a modification aid component. The active component A is selected from at least one of metal elements of group VIII, the active component B is selected from at least one of metal elements of group VIB, and the modification aid component is selected from at least one of elements of groups IB, IIA, IIB, IIIA, and VIA. The hydrogenation catalyst is characterized by a TEM-EDS method, and the content of the modification aid component distributed in an A-B-S active phase region accounts for 60% to 98% of the total content of the modification aid component.
A hydrogenation catalyst, the hydrogenation catalyst is a sulfided-state hydrogenation catalyst and comprises a carrier, an active component A, an active component B, and a modification aid component, wherein the active component A is at least one selected from the metal elements of group VIE, the active component B is at least one selected from the metal elements of group VIB, and the modification aid component is at least one selected from the elements of groups IB, IIA, IIB, IIIA, and VIA;
A preparation method for the hydrogenation catalyst, the method comprises the following steps:
